Background: Several outcome measures can be performed to assess and quantify mobility after a lower limb amputation. The Prosthetic Limb Users Survey of Mobility (PLUS-M) is a self-report instrument developed to assess mobility in prosthesis users. It has already been translated into different languages but not into Brazilian Portuguese.

Objectives: To perform the translation and cultural adaptation into Brazilian Portuguese of the PLUS-M and to assess its validity and reliability.

Study design: Observational cross-sectional study.

Methods: Translation and cultural adaptation were performed by following internationally recognized standards. To assess construct validity, the T-scores of PLUS-M/12-Item Short Form-Brazilian Portuguese (BR-12) item short form were correlated to the 2-Minute Walk Test and the scores from the Medical Outcomes Study 36-Short Form Health Survey domains by the Spearman correlation coefficient (ρ). A second administration of the PLUS-M/BR-12 was done by phone call to assess test-retest reliability.

Results: Some cultural adaptations were made to improve understanding. The PLUS-M/BR-12 T-scores of 61 participants showed a strong correlation between the scores of the 2-Minute Walk Test (ρ = 0.69) and the Physical Function domain of the 36-Short Form Health Survey (ρ = 0.83), and an excellent test-retest reliability (intraclass correlation coefficient = 0.90 [IC 95% = 0.833-0.943]; F (49,49) = 19,037; P < 0.001).

Conclusions: The PLUS-M/BR-12 demonstrated evidence of validity and reliability in assessing mobility in Brazilian adults with lower limb amputations who use a prosthetic device, and it is suitable for use in clinical care.

背景:可以采用几种结果测量来评估和量化下肢截肢后的活动能力。义肢使用者活动能力调查(PLUS-M)是一种评估义肢使用者活动能力的自我报告工具。它已经被翻译成不同的语言,但还没有被翻译成巴西葡萄牙语。目的:对PLUS-M进行巴西葡萄牙语的翻译和文化改编,并评估其效度和可靠性。研究设计:观察性横断面研究。方法:按照国际公认的标准进行翻译和文化改编。为了评估结构效度,采用Spearman相关系数(ρ)将PLUS-M/12项短表格-巴西葡萄牙语(BR-12)短表格的t得分与2分钟步行测验和医疗结果研究36-短表格健康调查领域的得分相关联。PLUS-M/BR-12的第二次注射是通过电话进行的,以评估重新测试的可靠性。结果:进行了一些文化适应以提高理解。61名被试的PLUS-M/BR-12 t-得分显示,2分钟步行测验(ρ = 0.69)与36-简式健康调查的身体功能域得分(ρ = 0.83)具有较强的相关性,且具有良好的重测信度(类内相关系数= 0.90 [IC 95% = 0.833-0.943];F(49,49) = 19,037;P < 0.001)。结论:PLUS-M/BR-12在评估使用假肢装置的巴西成年下肢截肢患者的活动能力方面证明了有效性和可靠性,适合在临床护理中使用。

Objectives: The aim of this study was to systematically review the literature to identify factors that may influence quality of life in people with lower-limb amputation (all etiologies). Our primary focus was on identifying factors that can be modified, enabling a more concentrated integration of these aspects into the care and treatment of amputated patients.

Data source: Medline (via Ovid) and Scopus were searched in January 2023 for studies assessing quality of life for people with lower-limb loss. Studies were included if they reported on factors that could influence quality of life. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed.

Study selection: Studies were identified and assessed independently by 2 reviewers.

Data extraction: Data were extracted by 2 independent reviewers.

Data synthesis: After removing duplicates, the search yielded 2616 studies, of which 24 met our inclusion criteria (cross-sectional n = 13; prospective n = 9; retrospective n = 2). The most commonly used quality-of-life instruments were the Short Form 36, followed by the World Health Organization Quality of Life-BREF and the EuroQoL 5 dimension. Younger age, traumatic etiology, unilateral or below-knee amputation, presence of comorbidities, and social integration were found to influence quality of life in people with lower-limb amputation, whereas sex and socioeconomic context do not seem to have a clear influence.

Conclusions: This systematic review of the literature identified several factors that influence quality of life in patients with lower-limb amputation. However, the results are not always consistent across studies and there is still no consensus on some factors. Conclusive findings regarding sex and socioeconomic status remain elusive, primarily because of substantial disparities observed across the literature. Future prospective longitudinal studies with clear a priori inclusion of a wide range of potential factors are needed to clarify the impact of the identified factors. Factors such as age, type of amputation, comorbidities and social integration should be considered in the management of patients with amputation.

研究目的本研究旨在系统回顾文献,找出可能影响下肢截肢患者(所有病因)生活质量的因素。我们的主要重点是找出可以改变的因素,以便将这些方面更集中地纳入截肢患者的护理和治疗中:2023 年 1 月,我们在 Medline(通过 Ovid)和 Scopus 上检索了评估下肢缺失患者生活质量的研究。如果研究报告涉及可能影响生活质量的因素,则将其纳入研究范围。研究筛选遵循《系统综述和元分析首选报告项目》指南:数据提取:数据提取:由两名独立审稿人提取数据:去除重复数据后,共搜索到 2616 项研究,其中 24 项符合我们的纳入标准(横断面研究 13 项;前瞻性研究 9 项;回顾性研究 2 项)。最常用的生活质量工具是简表 36,其次是世界卫生组织生活质量REF 和欧洲生活质量 5 维度。研究发现,较年轻的年龄、创伤性病因、单侧或膝下截肢、合并症的存在以及社会融合对下肢截肢者的生活质量有影响,而性别和社会经济背景似乎没有明显的影响:本系统性文献综述确定了影响下肢截肢患者生活质量的几个因素。然而,不同研究的结果并不总是一致的,对某些因素仍未达成共识。关于性别和社会经济地位的研究结果仍然难以确定,这主要是因为在不同文献中观察到的差异很大。未来需要进行前瞻性纵向研究,明确先验地纳入各种潜在因素,以澄清已确定因素的影响。在对截肢患者进行管理时,应考虑年龄、截肢类型、合并症和社会融合等因素。

Background: People with lower limb loss (LLL) have reduced physical activity (PA). There is evidence of physical and psychosocial predictors of PA in older adults with limb loss. However, these 2 areas (physical/psychosocial) have not been evaluated in the same analysis.

Objectives: To describe and identify predictors of PA in individuals with LLL.

Study design: Cross-sectional study.

Methods: Secondary analysis of data from a multisite Canadian randomized control trial involving community-dwelling prosthetic ambulators with unilateral transtibial or transfemoral amputation (N = 72). The dependent variable was the Physical Activity Scale for the Elderly. Potential predictors were four step square test, 2-minute walk test, Short Physical Performance Battery, Life Space Assessment, walking while talking test, and Activities-specific Balance Confidence scale.

Results: Seventy-two community-dwelling lower limb prosthesis users were enrolled. The sample included 62 male participants (86%), and 58 participants (81%) had transtibial amputation. The average age of participants was 65 (8.9) years, and for 49 participants (70%), the amputation was over 24 months ago. The total mean Standard Deviation (SD) Physical Activity Scale for the Elderly score was 153.2 (88.3), with scores of 148.1 (11.4) and 184.5 (24.7) for male and female participants, respectively. Regression analysis identified Life Space Assessment (β = 1.15, p = 0.007) and Short Physical Performance Battery (β = 3.51, p = 0.043) as statistically significant predictors accounting for 25% of the variance in PA.

Conclusions: Community mobility and physical performance are the most meaningful predictors of PA. Future research should examine additional factors (e.g., environment, motivation). Understanding the predictors for PA after LLL would improve clinical practice as clinicians would have increased knowledge to modify and improve training.

背景:下肢缺失(LLL)患者的体力活动(PA)会减少。有证据表明,肢体缺失的老年人在身体和社会心理方面的预测因素对体育锻炼有影响。然而,这两个方面(身体/社会心理)尚未在同一分析中进行评估:研究设计:横断面研究:研究设计:横断面研究:对加拿大一项多站点随机对照试验的数据进行二次分析,该试验涉及居住在社区的单侧经胫骨或经股骨关节截肢的假肢矫形者(N = 72)。因变量为老年人体力活动量表。潜在预测因素包括四步方格测试、2分钟步行测试、短期体能测试、生活空间评估、边走边说测试和特定活动平衡信心量表:72名居住在社区的下肢假肢使用者参加了研究。样本中有 62 名男性参与者(占 86%),58 名参与者(占 81%)有经胫截肢。参与者的平均年龄为 65(8.9)岁,其中 49 人(70%)的截肢时间超过 24 个月。老年人体力活动量表的总平均标准差(SD)为 153.2(88.3)分,男性和女性参与者的得分分别为 148.1(11.4)分和 184.5(24.7)分。回归分析表明,生活空间评估(β = 1.15,p = 0.007)和短期体能测试(β = 3.51,p = 0.043)是具有统计学意义的预测因素,占 PA 变异的 25%:结论:社区流动性和体能表现是对运动量最有意义的预测因素。结论:社区流动性和体能表现是最有意义的运动量预测因素,未来的研究应考察其他因素(如环境、动机)。了解 LLL 后 PA 的预测因素将改善临床实践,因为临床医生将掌握更多的知识来修改和改善训练。

Toward subtalar joint axis-driven computer-aided design and computer-aided manufacturing foot orthoses: Reliability of a noninvasive clinical scanning protocol. 实现以足底关节轴为驱动的计算机辅助设计和计算机辅助制造足部矫形器:无创临床扫描方案的可靠性。
IF 0.8 4区 医学 Q4 ORTHOPEDICS Pub Date : 2025-02-01 Epub Date: 2024-03-22 DOI: 10.1097/PXR.0000000000000343

Background: The subtalar joint axis (STJA) occupies a key role in the dynamics of the lower limb kinetic chain, and its location has a wide interindividual variability. It has been suggested that considering the STJA location when designing foot orthoses may help to apply the required mechanical dose. However, the evidence is more anecdotal than empirical.

Objective: This study aimed to evaluate the reliability of the STJA digitization, a procedure combining the clinical determination of the functional STJA location and its subsequent 3-dimensional (3D) scanning.

Study design: Two examiners identified the posterior and anterior exit points of the functional STJA on the skin of 15 healthy participants using a clinical method in a repeated-measure design.

Methods: A handheld 3D scanner was used to scan the feet and the skin markers. The 3D coordinates of the skin markers were subsequently quantified and (1) STJA digitization intratester within-session, (2) STJA digitization intratester between-session, and (3) STJA digitization intertester between-session reliabilities were evaluated.

Results: When pooling all skin marker 3D coordinates, intraclass correlation coefficients (ICCs) for the STJA intratester within-session reliability ranged from 0.74 to 0.98. ICCs for the STJA digitization intratester between-session reliability ranged from 0.58 to 0.94. ICCs for the STJA digitization intertester reliability ranged from 0.56 to 0.81. Standard error of measurement for the mediolateral position of the talus marker (anterior exit point of the STJA) was substantially higher than that for the other coordinates.

Conclusions: Overall, the STJA digitization demonstrated a good intratester between-session reliability and may be used in a computer-aided design and computer-aided manufacturing workflow to create foot orthoses. However, further efforts should be considered to improve the scanning process and intertester reliability.

背景:足底关节轴(STJA)在下肢运动链的动力学中起着关键作用,其位置在个体间存在很大差异。有人认为,在设计足部矫形器时考虑 STJA 的位置可能有助于应用所需的机械剂量。然而,这些证据更多的是传闻,而非实证:本研究旨在评估 STJA 数字化的可靠性,这是一种结合临床确定功能性 STJA 位置和随后进行三维(3D)扫描的程序:研究设计:两名检查者采用重复测量设计,使用临床方法确定 15 名健康参与者皮肤上功能性 STJA 的后方和前方出口点:方法:使用手持式三维扫描仪扫描脚部和皮肤标记。方法:使用手持式三维扫描仪扫描脚部和皮肤标记,然后量化皮肤标记的三维坐标,并评估(1)STJA数字化治疗师在治疗期间内的可信度;(2)STJA数字化治疗师在治疗期间内的可信度;(3)STJA数字化治疗师在治疗期间内的可信度:将所有皮肤标记的三维坐标汇总后,STJA 检测器内部的会话间可靠性的类内相关系数(ICCs)介于 0.74 和 0.98 之间。STJA 数字化室内测评仪两次测评间可靠性的 ICC 为 0.58 至 0.94。STJA 数字化测试者间信度的 ICC 为 0.56 至 0.81。距骨标记内外侧位置(STJA 的前出口点)的测量标准误差远高于其他坐标:总的来说,STJA 数字化在两次测量之间表现出良好的可靠性,可用于计算机辅助设计和计算机辅助制造工作流程,以制作足部矫形器。不过,应考虑进一步改进扫描过程和测试者之间的可靠性。

Background: Returning to work is a key outcome of rehabilitation and social re-integration after lower limb amputation. It is important to understand what biopsychosocial factors contribute to returning to work after dysvascular amputation.

Objective: Examining relative contributions of functional and contextual predictors of returning to work in participants with lower limb amputation due to diabetes and other dysvascular diseases.

Study design: Cross-sectional.

Methods: Return-to-work outcome, biopsychosocial characteristics including physical functioning, self-efficacy & perceived ability, and socioeconomical support data were collected from a purposive sample (n = 57) in a multi-state collaborative research network. Grouped Weighted Quantile Sum model analysis was conducted to evaluate relative contributions of biopsychosocial predictors.

Results: Less than 30% of the participants returned to work after their amputation. Physical functioning (odds ratio = 10.19; 95% CI 2.46-72.74) was the most important predictor group. Working before amputation, prosthetic mobility, and access to rehabilitation care were also identified as key factors associated with returning to work.

Conclusions: Fewer than 1 in 3 participants with dysvascular amputation returned to work, despite an average age of only 54 years at the time of amputation. Physical functioning was shown to be the most important predictor, while socioeconomic factors such as a lack of access to care also contribute to not returning to work after dysvascular amputation.

背景:重返工作岗位是下肢截肢后康复和重新融入社会的关键成果。了解哪些生物心理社会因素有助于血管性截肢后重返工作岗位非常重要:研究设计:横断面研究:研究设计:横断面:研究设计:横断面研究。方法:从一个多州合作研究网络中的特意样本(n = 57)中收集重返工作结果、生物心理社会特征(包括身体功能、自我效能和感知能力)以及社会经济支持数据。通过分组加权量子和模型分析,评估生物心理社会预测因素的相对贡献:结果:不到 30% 的参与者在截肢后重返工作岗位。身体功能(几率比=10.19;95% CI 2.46-72.74)是最重要的预测因素。截肢前的工作、假肢的活动能力和获得康复护理的机会也被认为是与重返工作岗位相关的关键因素:结论:尽管截肢时的平均年龄仅为 54 岁,但只有不到三分之一的血管截肢患者重返工作岗位。身体功能被证明是最重要的预测因素,而社会经济因素(如缺乏获得护理的途径)也是导致血管截肢后无法重返工作岗位的原因。

Limited data are available related to using a low-cost prosthetic knee while walking. To address this gap, this study compared the performance of a low-cost prosthetic knee with 2 more advanced prosthetic knees while walking on even and uneven terrains. Two adult subjects with above-knee amputations completed walking trials using a low-cost prosthetic knee (ReMotion knee) and their personal prosthetic knees (Ottobock 3R60 Pro mechanical knee and Ossur Rheo microprocessor knee) over even and uneven terrains. Several measures of gait performance were obtained including step size, stability, energy expenditure, as well as user perception of ReMotion workload and performance during gait. Effects of the ReMotion knee were different between the mechanical and microprocessor knee user. In addition, subjects perceived the positive aspects associated with the ReMotion knee to be its lightweight feature and their perceived increased in stability during walking while both subjects disliked the inability of the ReMotion knee to adjust to preferred walking speeds. This study provided an understanding of low-cost prosthetic technology among lower-limb amputees compared to prosthetic technology with more technologically advanced assistance. These findings may help guide future low-cost prosthetic knee design considerations for use on various terrains.

有关在行走时使用低成本义肢膝关节的数据非常有限。为了填补这一空白,本研究比较了低成本义肢膝关节和两个更先进的义肢膝关节在平坦和不平坦地形上行走时的表现。两名膝上截肢的成年受试者使用低成本义肢膝关节(ReMotion 膝关节)和他们的个人义肢膝关节(Ottobock 3R60 Pro 机械膝关节和 Ossur Rheo 微处理器膝关节)在平坦和不平坦的地形上完成了行走试验。对步态性能进行了多项测量,包括步幅、稳定性、能量消耗以及用户对 ReMotion 膝关节在步态过程中的工作量和性能的感知。机械式膝关节和微处理器膝关节使用者对 ReMotion 膝关节的使用效果存在差异。此外,受试者认为 ReMotion 膝关节的积极方面在于其轻便的特点以及在行走过程中稳定性的提高,而两个受试者都不喜欢 ReMotion 膝关节无法根据偏好的行走速度进行调整。这项研究让我们了解了下肢截肢者使用的低成本假肢技术与技术更先进的辅助假肢技术之间的比较。这些发现可能有助于指导未来在各种地形上使用低成本义肢膝关节的设计考虑。

Objective: The aim of this study was to assess the cultural adaptation and validation in Italian of the Seated Postural Control Measure for Adults 2.0 (SPCMA 2.0).

Methods: The original scale was translated and culturally adapted from French to Italian using the "Translation and Cultural Adaptation of Patient Reported Outcomes Measures-Principles of Good Practice" guidelines. Its internal consistency and test-retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Italian version of the Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Results: Fifty-nine people were evaluated and re-evaluated after 48 h. Most of the items and subscale totals were stable in the 2 evaluations as they reported an intraclass correlation coefficient value of >0.77. The test-retest analysis of the dynamic evaluation was performed on the same patients 48 h apart. The analysis for construct validity showed statistically significant correlations with Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Conclusions: Seated Postural Control Measure for Adults 2.0 is one of the few tools that allow researchers to perform a quantitative and standardized posture assessment in a cost-effective and time-saving way. Furthermore, it has been demonstrated that it is an easy-to-administer scale and requires readily available tools. The limitations of this study highlighted above and the need to use quantitative and qualitative tools in clinical practice imply the need to conduct future studies.

目的:本研究旨在评估成人坐姿控制测量 2.0(SPCMA 2.0)的文化适应性和意大利语验证:本研究旨在评估成人坐姿控制量表 2.0(SPCMA 2.0)在意大利语中的文化适应性和有效性:方法:采用 "患者报告结果测量的翻译和文化适应性--良好实践原则 "指南,将原始量表从法语翻译成意大利语并进行文化适应性调整。对其内部一致性和重测可靠性进行了检验。使用与意大利语版轮椅使用信心量表和轮椅技能测试 4.2 的皮尔逊相关系数对其并发有效性进行了评估:大多数项目和分量表的总分在两次评估中都保持稳定,因为它们的类内相关系数大于 0.77。动态评估的重复测试分析是在相隔 48 小时的同一患者身上进行的。结构效度分析表明,该量表与轮椅使用信心量表和轮椅技能测试 4.2.结论具有统计学意义的相关性:成人坐姿控制测量 2.0 是少数几种能让研究人员以经济、省时的方式进行定量和标准化坐姿评估的工具之一。此外,它还被证明是一种易于使用的量表,只需使用现成的工具即可。上文强调了本研究的局限性,以及在临床实践中使用定量和定性工具的必要性,这意味着有必要开展未来的研究。

Effect of pain on activity and participation in individuals with unilateral lower-extremity amputation based on the International Classification of Functioning, Disability, and Health. 根据国际功能、残疾和健康分类,疼痛对单侧下肢截肢者活动和参与的影响。
IF 0.8 4区 医学 Q4 ORTHOPEDICS Pub Date : 2025-02-01 Epub Date: 2024-03-22 DOI: 10.1097/PXR.0000000000000342

Background: Amputation is a major life-changing event and is regarded as one of the loading causes of permanent disability. However, amputation often causes changes in painful and nonpainful sensory experiences. Pain after amputation has been shown to increase functional limitations caused by limb loss and lower quality of life.

Objective: This study aimed to examine the effect of pain on activity and participation in individuals with unilateral below-knee amputations according to the International Classification of Functioning, Disability, and Health.

Study design: Cross-sectional study.

Methods: In the study, 64 individuals were divided into 2 groups: those who experienced pain and those who did not. Group 1 included 33 below-knee amputees who experienced pain (27 males, mean age 43.9 ± 12.6 years) and Group 2 included 31 below-knee amputees who did not experience pain (25 males, mean age 47.4 ± 12.1 years). The McGill Pain Questionnaire and visual analog scale were used to assess pain, the Prosthetic Limb Users Survey of Mobility was used to assess activity, and the Reintegration to Normal Living Index was used to assess participation.

Results: Demographic characteristics of the 2 groups were statistically insignificant ( P > 0.05). The nonpainful group had significantly higher activity and participation scores than the painful group ( P < 0.001).

Conclusions: It was found that phantom pain and stump pain in below-knee amputees limited activity and participation. It was also shown that phantom pain has a more negative effect on the activity level of individuals than stump pain.

背景:截肢是改变人生的重大事件,被认为是造成永久性残疾的主要原因之一。然而,截肢往往会引起疼痛和非疼痛感觉体验的变化。事实证明,截肢后的疼痛会增加因肢体缺失造成的功能限制,并降低生活质量:本研究旨在根据《国际功能、残疾和健康分类》研究疼痛对单侧膝下截肢者活动和参与的影响:研究设计:横断面研究:研究将 64 名患者分为两组:有疼痛感和无疼痛感。第一组包括 33 名有疼痛感的膝下截肢者(27 名男性,平均年龄为 43.9 ± 12.6 岁),第二组包括 31 名没有疼痛感的膝下截肢者(25 名男性,平均年龄为 47.4 ± 12.1 岁)。麦吉尔疼痛问卷和视觉模拟量表用于评估疼痛,假肢使用者活动能力调查用于评估活动能力,重新融入正常生活指数用于评估参与情况:两组患者的人口统计学特征差异无统计学意义(P>0.05)。非疼痛组的活动和参与评分明显高于疼痛组(P < 0.001):结论:研究发现,膝下截肢者的幻痛和残肢痛限制了他们的活动和参与。结论:研究发现,膝下截肢者的幻痛和残端痛限制了他们的活动和参与,而且幻痛对个人活动水平的负面影响大于残端痛。

Background: Pressure, shear stress, and friction can contribute to soft tissue damage experienced by a residual limb. Current compression/release stabilized (CRS) socket designs may pose a risk to soft tissue from abrupt compression differences within the socket.Objectives:Density-graded lattice structures are investigated for their potential to mitigate risk of tissue damage by assessing their ability to produce more gradual transitions between high-compression and low-compression areas.Study Design:A full factorial experimental design was used to reveal the effects of changes among three variables: lattice geometry, density alteration, and displacement magnitude. A total of 144 experimental conditions were examined.

Methods: Lattice samples representing areas of compression and release based on a novel cushioned transhumeral level CRS style socket design were 3D printed. Compression testing was performed on 2 types of lattice structures which incorporated 1 of 8 design elements to alter density and axial stiffness. The effect on stiffness of the sample as a function of lattice type and density alteration was recorded under 3 loading conditions.

Results: The offset diamond lattice type with blend radius density alterations produced the only samples meeting criteria set for compression areas of the socket. No samples satisfied criteria for release areas. Transitional density lattices that gradually tapered between the best performing compression and release values were successfully produced.

Conclusions: Transitional density lattices offer promise for mitigation of soft tissue damage through minimization of compression differentials throughout the socket. Wider implications for this research include use in sockets for other levels of amputation and in orthotics. Future work will focus on lattice optimization to improve release behavior within a modified CRS socket.

背景:压力、剪切应力和摩擦力会造成残肢软组织损伤。研究设计:采用全因子实验设计来揭示三个变量之间变化的影响:晶格几何形状、密度变化和位移幅度。共研究了 144 种实验条件:方法:根据新型缓冲式跨肱骨水平 CRS 型插座设计,3D 打印了代表压缩和释放区域的晶格样本。对 2 种晶格结构进行了压缩测试,这些结构包含 8 个设计元素中的 1 个,可改变密度和轴向刚度。在 3 种加载条件下,记录了网格类型和密度变化对样品刚度的影响:结果:只有偏置金刚石晶格类型和混合半径密度改变产生的样品符合插座压缩区域的标准。没有样品符合释放区域的标准。在最佳压缩值和释放值之间逐渐变细的过渡密度晶格被成功生产出来:过渡密度网格有望通过最大限度地减少整个牙槽窝的压缩差来减轻软组织损伤。这项研究的更广泛意义包括将其用于其他程度的截肢和矫形。未来的工作重点是优化晶格,以改善改良 CRS 承插器内的释放行为。

Predicting adherence to ankle-foot orthoses in people with stroke: An application of the Theory of Planned Behavior. 预测中风患者对踝足矫形器的依从性:计划行为理论的应用。
IF 0.8 4区 医学 Q4 ORTHOPEDICS Pub Date : 2025-02-01 Epub Date: 2024-09-05 DOI: 10.1097/PXR.0000000000000370

Background: Ankle-foot orthoses (AFOs) are often prescribed for people with stroke to address motor impairment. However, not all patients adhere to using their AFOs as prescribed. Predictors of AFO adherence are likely to constitute useful targets for interventions that aim to promote this behavior.

Objective: To identify the predictors of AFO adherence in people with stroke using an established theoretical framework, namely the Theory of Planned Behavior (TPB; Ajzen, 1991).

Study design: Prospective survey design.

Method: N = 49 people who had been prescribed an AFO after a stroke completed a TPB questionnaire. One month later, they completed another questionnaire that measured adherence to AFOs as prescribed by an orthotic practitioner. Predictors of intention and AFO-adherence behavior were identified using regression analyses.

Results: Adherence to AFOs was 63%. The TPB accounted for 61% of the variance in intentions and 43% of the variance in AFO-adherence behavior. Attitude and perceived behavioral control were predictors of intention, and intention was the sole predictor of behavior.

Conclusion: The TPB is a useful model for explaining adherence to AFOs in people with stroke. Interventions could be designed to increase intentions to use an AFO as prescribed by promoting positive attitudes towards, and perceived behavioral control of AFO adherence.

背景:踝足矫形器(AFO)通常用于中风患者,以解决运动障碍问题。然而,并非所有患者都能按处方坚持使用踝足矫形器。踝足矫形器坚持使用的预测因素很可能成为旨在促进这一行为的干预措施的有用目标:利用已有的理论框架,即计划行为理论(TPB;Ajzen,1991 年),确定中风患者坚持使用 AFO 的预测因素:研究设计:前瞻性调查设计:N = 49 名中风后被开具 AFO 的患者填写了一份 TPB 问卷。一个月后,他们完成了另一份调查问卷,该问卷用于测量矫形医师开具的 AFO 的依从性。通过回归分析确定了意向和坚持使用AFO行为的预测因素:结果:坚持使用 AFO 的比例为 63%。TPB解释了61%的意向差异和43%的AFO坚持行为差异。态度和感知行为控制是意向的预测因素,而意向是行为的唯一预测因素:TPB是解释中风患者坚持使用AFO的有效模型。可以设计干预措施,通过促进对坚持使用 AFO 的积极态度和感知到的行为控制来提高按处方使用 AFO 的意愿。
